title	Rosario, Views on the Integral Revitalization of a Cultural Heritage
source	SIGraDi 2006 - [10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006
summary	This work shows the study of the methods and techniques for the development of a virtual vision VRML 3D included in an "Digitally-integrated knowledge base" with interactive interphases of a significantly revitalized fragment of a central area of the city of Rosario, Province of Santa Fé, Argentina, that includes an emblematic heritage for the Argentineans: the National Monument to the Flag. Digital models that partly allow the development of a hypothesis of integration between the digitized information and information technology - new digital proximity - to the effects of being able to investigate the generation of multimedia database that includes three-dimensional and dynamic models of the mentioned type, in this case, urban, architectonic, and cultural heritage. Different views and research on heritage have been developing. Nevertheless, the use of these new 3D non-immersive technologies and inter-phases are opening a new field of vision and understanding of the subject.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title	APPLICATIONS OF THE DIGITAL MODEL DATABASE FOR TAIWAN CITY AND ARCHITECTURE: The interactive entertainment platform
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 581-583
doi	https://doi.org/10.52842/conf.caadria.2006.x.d1a
summary	In Taiwan, the National Science Council (NSC) has launched the “National Digital Archives Program” (NDAP) since 2002. We participated in two projects: “The 3D digital museum of Taiwan city and architecture” and “Digital model database and professional service for Taiwan city and architecture”. The first one attempted to build a virtual museum for Taiwan city and architecture through the past four hundred years. The second one was a value-added project which intended to further apply the digital contents of the previous one. This project was consisted of 3D refined data, digital knowledge database, and architecture professional service. We were responsible for the 3D refined data. As a result, the digital model database included three cities: Hsinchu, Chiayi, and Tainan, as well as sixty-four architecture models. The interactive entertainment platform is an important leisure in our daily life. In general, the interactive entertainment includes five types: arcade game, PC game, on-line game, TV game, and mobile entertainment. This research pays attentions to the arcade game which presents dynamic interactions between machine and users. Following the improvements of design techniques, we have opportunities to experience many arcade games with different purposes, such as drum game, dance game, and fishing simulator. However, we further apply the digital model database to create an interactive entertainment platform for a racing arcade game.

title	A cidade que nunca existiu: modelos 3D da história da cidade [The City that never Existed: 3D Models of the City History]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 381-385
summary	Through the evaluation of advantages and limitations of 3D historic city models, this paper aims to analyze the contribution of those tools to the city history representation. One should overcome limitations such as incomplete information, impediments to acknowledge hypotheses representations, intense labor requirements or difficulties to encourage a deep reflection. We identify some significant characteristics of those systems based on historical facts’ location in 3D models, different files association, dynamic databases and interaction, which should prevail over some of the limitations. Finally, we illustrate those issues through the system Rio-H that presents an alternative for historical narratives.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

summary	Forty years of development have passed since digital technologies were used in the service of design for the first time but many of the early questions about its usefulness are still open. The beginning [early] period, known as call “analytical”, was founded in a rational and reductionist understanding of the phenomenon, including those related to creative processes. The target was rational optimization for possible solutions around a given problem. Later on, the graphic technologies development meant a huge jump in issues concerning 3D representation of designed objects. A great interest in visualization and “the virtual” then arose: almost everything and any shape, could be modelled and visualized, obtaining representations of space, time, light and matter as never seen before in any field related to imaging. Today these useful technologies are amplified due to the connectivity of the web, stimulating the birth of applications and models which seek to optimize the production processes. However, before of its impact, there is still a question waiting to be answered since the first days of CAD: has all this technology actually allowed the development of better design? The answer doesn’t seem to be obvious, when above all we see ourselves facing the context of a global world that becomes more and more complex. Digital technology is developing very rapidly. Despite this, an equally accelerated improvement in design products is not so clear. The reason for this could be the fact that our practices as designers have not been updated and improved at the same speed as technology. This next Sigradi is about debating how our organizational practices are changing with the digital phenomenon and how the users can positively trigger the potential that lies in these technologies. The hypothesis that underpins this question is the consideration that digital technologies are a unique platform to achieve the necessary integration of knowledge that must feed any contemporary design process. We think that the integration of multidisciplinary knowledge, memories, values and imagination must become the starting point in the production of better design.

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

summary	Digital workflows from the design to the production of buildings have received significant recent attention in architectural research. The need for both integrated systems for design collaboration (Boeykens and Neuckermans, 2006) and clear and flexible communication flows for non-standard fabrication outcomes have been identified as fundamental (Scheurer, 2010). This paper reports on the development of a digital “design system” for the design and prototyping of an acoustic enclosure for meetings in a large open work environment, theFabPod. The aim was to keep this system open for temporal flexibility in as many aspects of the finalisation of the design as possible. The system provides novel examples of both integrated collaboration and clear communication flow. (1) Acoustics is included as a design driver in early stages through the connection of digital simulation tools with design models. (2) Bi-directional information flows and clear modularisation of workflow underpins the system from design through to fabrication and assembly of the enclosure. Following the completion and evaluation of the FabPod prototype, the openness of the system will be tested through its application in subsequent design and prototyping iterations. Design development will respond to performance testing through user engagement methods and acoustic measurement.

summary	Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

title	Fascination google earth – use in urban and landscape design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 141-148
summary	Virtual 3D-City-and Architecture models, Virtual Globe systems like NASA World Wind and Google Earth as well as new attempts of immersive technologies become more important, not only among experts in spatial planning, but also many private users are interested in these new tools. These developments cause powerful impacts in the general social, cultural and everyday life. Given the dynamic development of Google Earth, the discussion about the representation and the use of geodata for a wide user group - beyond the planning disciplines - reaches new heights. According to expert's opinion, Google Earth with its computer language KML (Keyhole Markup Language) becomes a 3D-GIS-Standard [Rush in 2006]. By the easy and quick representation of three-dimensional (city) structures and single buildings, Google Earth will significantly influence all groups of society. User groups which have not been acquainted with geodata or highly specified and complex GIS-Systems [Dworschak in 2006], discover that working with this data by using Google Earth is great fun. They recognize, that with the help of generally understandable and easily recognizable visualisation of these data, mediation of knowledge becomes very easy. In addition, it is acknowledged that geodata has great potential to add value, in disciplines such as the academics, the financial sector or personal use.

summary	For a contribution to problem solving processes at different areas, this paper presents the use of Digital Graphics as a knowledge object for a distance teaching/learning workshop. At the Learning Management System, different theoretical subjects with supporting tools were proposed, and exercises requiring collaborative work. An specific didactic situation using available technologies at Internet for 3D modelling, combined with satellite images and geographic information program was proposed. The final works were then shared by a 3D models repository. As a complement of this experience and in relation with their professional work, every student proposed a new didactic situation including Learning Objects, sharing them with the others members of the group, through conceptual maps built up in a co-operative way.

source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	Optimization in the Balance between the Production Effort of E-learning Tutorials and their related Learning Outcome
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 122-126
summary	This paper provides evidence on the level of media richness that may be cost effective in the development of e-learning tutorials for teaching and learning computer visualization techniques. For such a purpose the author provides an analysis of low-cost / high-impact media rich products, the effort and cost required in their development and the measurement of related learning outcomes. Circa twenty years of R&D of multimedia and hypermedia applications for instruction have demonstrated the benefits of communicating relevant information to learners using engaging media. Based on this evidence, this paper assumes that due to the cognitive style of design students, the instructional packages for learning computer techniques for design visualization that are rich in media content, tend to be more effective. Available visualization technologies make the development of e-learning tutorials feasible and apparently the logical way to implement our instructional packages. However the question in the development of e-learning tutorials becomes a more strategic one when we are called to reach a level of optimization between producing a package with a basic standard, namely; text & still-graphic based tutorials, or a state-of-the-art package that is based on video demonstrations (more than enough?) that can accommodate the students’ learning requirements and also our production costs. The costs include the human resources (instructor, producers, assistants and others) and the material resources (hardware and software, copies, and others) involved in the creation of the e-learning tutorials. The key question is: What is good enough, and what is clearly superfluous? In order to confirm our hypothesis and propose a relevant balance between media richness and learning effectiveness, this paper describes an experiment in the use of two different levels of media richness as used to deliver instructions on the production of computer animations for design visualization. The students recruited for this experiment were fairly familiarized with the use of 3D modeling concepts and software, but had no previous knowledge of the techniques included in the tutorials; in specific; camera animation procedures. The students, separated in two groups, used one of the two methods; then they proceeded to apply their newly acquired skills in the production of an animation without using the help of any external means. The assessment of results was based on the quality of the final product and the students’ performance in the recall of the production procedures. Finally an interview with the students was conducted on their perception of what was accomplished from a metacognitive point of view. The results were processed in order to establish comparisons between the different levels of achievement and the students’ metacognitive assessment of learning. These results have helped us to create a clear set of recommendations for the production of e-learning tutorials and their conditions for implementation. The most beneficial characteristics of the two tested methods in relation to type of information, choice of media, method of information delivery, flexibility of production/editorial tools,! and overall cost of production, will be transferred into the development of a more refined product to be tested at larger scale.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
doi	https://doi.org/10.52842/conf.acadia.2006.232
summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

The new white, minimalist four-story building, designed by a Tokyo architect, is a stacked four unit multi-family dwelling with a garage and two large professional photography studios for lease on its ground floor. Located in the Ota-ku area of the city, the site was previously occupied by the owner with a sprawling residence that was wrapped by a layer of dense vegetation, and was unique in a city where open space is rare amidst the high demand for built space. Since the entire site is to now be razed to accommodate construction for the new and much larger development, the design intention for the screen is to invent an architectural system that performs with similar attributes to the demolished green strip and creates an atmospheric zone of protection. In effect, the demolished two meters of setback width of open ground space is now to be reduced into a new zone with a width of only 20 cm.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Experimenting with 3D Digitization of Architectural Physical Models using Laser Scanning Technology
source	International Journal of Architectural Computing vol. 4 - no. 2, 67-80
summary	This paper assesses the use of 3D Digitization techniques by carrying out laser scanning of typical physical models produced by architecture students. The aim was to examine the product of laser scanning with respect to scanning and 3D modeling processes, and the effects of variables such as characteristics of the models, materials used, and design complexity. In order to assess the similarities and accuracies achieved by the scanning and 3D modeling processes, the research investigated human perception of differences between analogue and digital models. This enabled an assessment of the degree to which digital models were accurate representations of the real ones, and whether laser scanning can successfully be used as a medium to recreate and represent complex architectural physical models. The study presents a potential direction for digital translation in architectural education.

title	Teaching parametric design in code and construction
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary	Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.
